What do you like about my artwork?

Just a random question that I got today

It's been 5 days since I drew something 'decent' and today I decided to practice some more while watching video lessons on head structure, face, hands, etc.
During these days that I've been drawing not-so-good stuff I started asking myself, why you guys like my drawings? 

This is probably my self-critic harassing me inside my head, but I've noticed that I'm very inconsistent with my drawings. As in I could draw one character (be from media or an OC) and it would most likely not look "the same" if I drew it a second time (hence the reason why in my 30 day OC challenge, Iriana looks quite different in every drawing).

I don't know, really. This was just something I wanted to get out of my chest and I wanted to hear your thoughts on it.
